Abstract
The utility model belongs to the field of heat exchange finned pipes. A heat exchange finned pipe with a temperature compensating groove consists of a heat exchange pipe and a fin, wherein one end of the fin is fixedly connected with the heat exchange pipe. The heat exchange finned pipe with the temperature compensating groove is characterized in that the fin is provided with a groove. Compared with the prior art, the fin is provided with the groove, therefore, the heat exchange area of a unit heat exchange finned pipe is increased; the defrosting is easy; a temperature compensating effect is achieved; and the groove can further buffer tensile stress.
Description
Technical field
The utility model belongs to the heat-exchange finned tube field, especially for the heat-exchange finned tube in the air-heating type gasifier of liquified natural gas gasification.
Background technology
The gasifier of domestic use has electrothermal, electrothermal water bath type, hot water circuit formula, air temperature type several, and the advantage of air-heating type gasifier is that expense is well below other gasifier.Therefore, be subjected to user's favor day by day.The core of air-heating type gasifier is exactly the finned tube assembly, obtains powerful heat energy in as far as possible little space from atmosphere.The finned tube assembly of present air-heating type gasifier adopts the aluminum alloy fin pipe to combine more.Have following shortcoming mostly: equipment is huge, cost is too high, product flow is not enough.The operation principle of finned tube is that example is done following analysis with liquefied petroleum gas as working media: when liquefied petroleum gas mobile (vertical axial direction from bottom to top) in pipe, at first finish and heat exchange with outside near finned tube inwall liquid in the middle of the cold fluid, this process realized cold fluid from-196 ℃ of liquid state to the conversion that is lower than 10 ℃ of gaseous states of environment temperature, its process need absorbs a large amount of heats.
Heat-exchange finned tube heats to achieve from liquid state by the fluid in the heat in the absorbing environmental (as air) the exchange heat pipe and is converted to gaseous state.Common heat exchange fin tubular construction is heat exchanger tube and eight affixed with it or 12 fins thereof, and the long 7～8cm of fin, width change with the variation of air-heating type gasifier amount of vaporization size, are generally 1～10m, thick 1.5～2mm.Heat exchanger tube is mainly carried fluid and heat exchange, fin mainly absorbs airborne heat, therefore the temperature of heat-exchange finned tube also will experience from-196 ℃ to the variation that is lower than 10 ℃ of environment temperatures, fin profile is a straight-plate-type, usually adopt main fin and secondary fin thereof to form, this kind structure exists following drawback or deficiency:
(1) because fin profile is straight plate, frost is strong with the fin adhesion after the frosting, is difficult for defrosting;
(2) because fin profile is straight plate, when connecting use, meet cold contraction, have tension between main fin, have fin distortion, twisted phenomena, potential safety hazard is arranged.
The utility model content
The utility model is intended to overcome above-mentioned drawback and deficiency, and a kind of heat-exchange finned tube that has the temperature-compensating groove is provided.
The heat-exchange finned tube that has the temperature-compensating groove, the fin affixed by heat exchanger tube and an end and heat exchanger tube constitutes, and it is characterized in that described fin is provided with groove.
Compared with prior art, the utility model has increased the heat exchange area of unit heat-exchange finned tube because fin is provided with groove, is easy to defrost, has played the effect of temperature-compensating; Groove can also cushion tension.
Description of drawings
Fig. 1 is the utility model structural representation, wherein: the 1-joint angle; 2-groove A; 3-master's fin; The secondary fin of 4-; 5-groove B; The 6-heat exchanger tube; The 7-fillet.
The specific embodiment
Referring to accompanying drawing 1, have the heat-exchange finned tube of temperature-compensating groove, the fin affixed by heat exchanger tube 6 and an end and heat exchanger tube constitutes, and it is characterized in that described fin is provided with groove.
Described fin comprises main fin 3 and secondary fin 4, main fin 3 and secondary fin 4 uniformly at intervals, main fin, plays and supports and the effect that is connected during air-heating type gasifier in assembling, secondary fin does not then participate in connection.
Groove A2 on the described main fin is an arc, is used to increase heat exchange area, is easy to defrost, alleviates the effect of shrinkage deformation force simultaneously in addition.
Groove B5 on the described secondary fin is an acute angle shape, is used to increase heat exchange area, is easy to defrost, alleviates the effect of shrinkage deformation force simultaneously in addition.
Described main fin long 11～12cm, wide 1～10m, thick 2～3mm.
Described secondary fin size long 8～9cm, wide 1～10m, thick 2～3mm.Take to increase the size of major and minor fin, thereby increase single unit heat exchange area.
The end of described main fin is provided with the joint angle 1 of rhombus, the tie point and the strong point during as assembling.
The end of described secondary fin is provided with fillet 7, works to avoid scratching operating personnel.
Described main fin has 4, and it is uniform to be 90 degree with respect to heat exchanger tube, and secondary fin has 4 or 8, is distributed between the main fin.
The described heat-exchange finned tube that has the temperature-compensating groove adopts an extrusion modling of aluminium section bar.
Advantage of the present utility model and good effect
(1) the unit heat exchange area increases substantially than common finned tube, has the considerable energy saving environment protecting.
(2) defrost speed increases substantially than common finned tube, also has the considerable energy saving environment protecting.
(3) frost reduces than common finned tube is relative with the adhesion of fin after the frosting, is easy to defrosting.
(4) shut down the common fin pipe range of defrost interval time ratio, reduce and shut down number of times, save operating cost.
(5) reduce finned tube significantly and met the stress deformation that cold contraction causes, improved security and reliability.
(6) under equal heat exchange area condition, littler than common finned tube volume, reduced floor space, reduced construction cost.
